Speeication forming part of Letters Patent No. 159,287, dated April28,1874; application tiled October 25, 1873. y

To all whom it may concern:

Be it known that I, BENJAMIN-B. thrown, of Springeld, in the county ofWindsor and State of Vermont, have inventeda new and valuableImprovement in and I do herebydeclare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure l of thedrawings is a representation of my suspension-car inoperation.'

The object of myinvention is to provide for safely crossing rivers andehasms by means of a carriage which is suspended from a wire stretchedbetween posts located on opposite said carriage being moved from onepost to the vother by incliningy the wire, or by means ot' an endlessrope which is carried around pulleys on the posts, and also aroundpulleys on the carriage, as will be v height, I employ platformsWith-steps leadinghereiuat'tcr explained. Y

The following is a description of my invention: A

In-the annexed drawings, A A" represent two posts, which are arranged onopposite 'sides of a chasm, and properly braced, so as to maintain theirpositions rmly against any strain which they maybe. subjected to. Bvrepresents one or more wires, which are stretched between the ,two postsA A', and from which wires a car, C, is suspended by means of ilangedrollers a a. At` one end the wires 1 3 are iunnovably secured to thepost A', and'at their opposite ends they are secured to a tightening-drum, b, having its bearings in a vertically-adjustable block,D,on post A. The block l) is connected to the post A by means of tonguesand grooves and 12h Gla'SPwf/'I- 090' xed'into it, by means of which itcan be turned when it is desired to tighten the wire or wires B,

end/of the drum b has radial 'arms and by means of a removable stop-pin,d, inf

sorted into one of several holes in block D, the drum is prevented fromturning back.; Avertical rack, e,'is secured to the .block D, andreceived into a slot made through post A. The teeth of lthis rack eengage with a spurn-'heel, f, which is keyed cn a shaft, g, havingv itsbearings in the post A. On one end of the Suspension Cars',-

spurwheel shaft loosely applied, having a crank handle, h', fixed intoits face, by which it can be turned conveniently. Outside of the pulleyIl, and keyed on the shaft g, is a circular clutch-plate, i, having ahole through it to receive a pin, j, which is inserted through thisplate and into the pulley t when it is desired to pulley with its shaft,for the :purpose of depressing the block D. An endless rope, E, is'vapplied around the pulley h, and carried across the chasm, and passedaround another grooved pulley, j', which is applied to the post A', andto which a crank-handle is fixed. The ropelt is connected to the car Cby passing it around kit, applied to the back two grooved pulleys,

pulleys have crankot this carriage, which handles xed .to them.

In practice I shall employ, either on post A or carriage C, a device fortightening the endless rope E. y

When .the posts A A are of considerable up to them. G represents one ,ofthese platforms applied atthe-post A, and constructed so as to affordeasy access to the carriage C when moved upto said post. When theearriage C is in thel position last named, it is steadied` and'prevented from swinging back by means of a curved stop', p,which issecured to the post A.

'Itwill be seenfroin the above description that the carriage can-'bemoved from one post tothe other on the wire or wires B by turning thepulley h or the, pulley. j?, or either one of the pulleys k k.- 1

-If it isdesired to send the carriage fron the post A( to thepost Awithout turning either one of the pulleys, this can be done byloweringthe block D so as to incline'the suspension- Wires; and byhaving "the suspensionwires connected at both ends tovertically-adjustable blocks D, the carriage can be sent back yandthewires B by pulling on the upper part of the endless rope E, and thuslowering the g a grooved pulley, h, is

engage this by Letters Patent, is-

block D and that end of the wires which are attached toit. l Y

Itis obvious that my improvements might" be erected in parks 'and otherplaces, where they would afford a source of amusement'to children andothers.

What I claim as new, and desire to secure l. The endless rope and passedaround pulleys h j and posts A A', the pulley h being applied on theDshaft g of E, conneeted tu um suspended carriage C by'means of pulleysk 7.', Y

the spur-wheel f, and having eoinbned'with. it a clutch-Nate, andclutch-pin j, as and fop the purposes explained. l

2. The stop p, applied to post A opposite the 4l'ylatfornl G, for thepurpose described.
